Thomas Edison and the Lightbulb

When Edison and his staff were developing the incandescent light bulb, it took hundreds of hours to manufacture a single bulb. One day, after finishing a bulb, he handed it to a young errand boy and asked him to take it upstairs to the testing room. As the boy turned and started up the stairs, he stumbled and fell, and the bulb shattered on the steps. Instead of rebuking the boy, Edison reassured him and then turned to hi staff and told them to start working on another bulb. When it was completed several days later, Edison demonstrated the reality of his forgiveness in the most powerful way possible. He walked over to the same boy, handed him the bulb, and said, "Please take this up to the testing room."
